I was just looking at that - we don't run that test due to:
root@intel-corei7-64:/opt/ltp/testcases/bin# ./migrate_pages03 tst_test.c:770: CONF: require libnuma >= 2 and it's development packages
Daniel - is this something we should add?

Saw this. Might be a kernel bug.

I overlooked that we wait for ksm scan in setup(), so that is not the issue. You can see in output that it completed.
This is looking more like kernel bug at the moment. Using same setup, but with 4.18 kernel I see it completing in couple seconds:
